The U.S. Supreme Court has allowed the Trump administration’s ban on most migrants seeking asylum at the U.S.-Mexico border to take effect while legal challenges against it proceed. Wednesday’s order overturns a federal appeals court’s injunction against Trump’s policy, which bars migrants from seeking asylum in the United States unless they’ve first applied for refugee status in the countries they passed through on their way to the U.S. Two Justices — Sonia Sotomayor and Ruth Bader Ginsburg — dissented, with Sotomayor writing, “Although this Nation has long kept its doors open to refugees—and although the stakes for asylum seekers could not be higher—the Government implemented its rule without first providing the public notice and inviting the public input generally required by law.”
